Interpretive Summary:

Technical Abstract: Estimates of gross primary productivity (Pg) and ecosystem respiration (Re) were derived from 20 minute net CO2 fluxes monitored at five Northern Great Plains locations using light-response analysis. At the weekly scale, daytime ecosystem respiration ('day) was correlated (0.64
